The structure of coke affects its reactivity and strength, which directly influences its performance in the blast furnace. This review divides coke structures into chemical structure, physical structure, and …
The main share of metallurgical coke is consumed in the steel industry to produce hot metal, which, in turn, is used as the main ingredient to make steel (Babich et al., 2016).Nut and breeze cokes as undersieve products of metallurgical coke are also widely used in the steel industry and, namely, in the BF and sintering processes, …
The coke plays the role of the skeleton, which ensures the gas and liquid penetration through the blast furnace. The Coke reactivity index (CRI) and the coke strength after reaction (CSR) are the most widely used indexes to indicate the coke degradation potential in a blast furnace. A coke with good quality shows a lower CRI and …

Coke is one of the critical elements in iron production and Hickman, Williams & Company provides global sourcing for blast furnace coke. Hickman, Williams also supplies small metallurgical coke sizes such as nut coke, buckwheat coke and coke breeze from both domestic and global sources. These smaller sizes are used in various industrial ...
12.2.1 General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke. Metallurgical coke is used in iron and steel industry processes ...
Metallurgical coke is one of the key raw materials used in the blast furnace to reduce the ferrous burden (e.g., iron ore, sinter and pellets) to iron, which is the precursor step in the production of steel. In the blast furnace, metallurgical coke plays several essential roles, the most important of which are maintaining the permeability of ...
Metallurgical coke is an extremely quality-sensitive product for the ferrous industry and constitutes a significant proportion of the production costs. Our strategic tie-ups and deep relationships with major coke sources and on-ground presence across the supply chain ensures consistency of product quality and on-time delivery, thereby providing ...
performance in the blast furnace. This review divides coke structures into chemical structure, physical. structure, and optical texture according to their relevant characteristics. The focuses of ...
The production of metallurgical coke is highly techno-economically oriented with the application of appropriate technologies, such as stamp charging, where even the so-called inferior quality coals can be used for the production of coke. ... entire coke quantity received from coal and coke testing laboratory was crushed and prepared. The …
In this test, 1g of minus 0.2mm coal is mixed with 5g anthracite and placed in a crucible. A 100-115g steel weight is placed on top of the coal sample and then the …
Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking. Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces. Heat and pressure cause physical and chemical changes …
Whereas, coke plant coke samples, 25 kg coke from a gross sample collected by standard practice was crushed with the help of Jaw crusher. By proper …
It was crushed to a particle size of less than 0.15 mm, then dried in an oven at 105 °C for at least 4 h to ensure that all moisture was removed. The metallurgical coke, coke breeze and coal tar pitch were supplied by a steel company from Heilongjiang province. The obtained coke breeze or metallurgical coke were all screened and …
Metallurgical coke typically contains around 8 % to 12 % of mineral phases. The proportion of individual minerals present in coke can vary from coke to coke depending on the mineralogy of the original coals as well as the process conditions employed for carbonization. During carbonization, some minerals decompose and some …
A metallurgical coke sample from Boyacá (Colombia) was used in the grinding process. The original sample was crushed in a roll mill (Denver Equipment Co., Denver, CO, USA) and sieved under six mesh (3.35 mm). Product PSD is depicted in Figure 1, and the elemental and proximate analyses are shown in Table 1.
This paper reviews quality requirements of metallurgical coke for the blast furnace, coke structure, and relationships between structure and quality. Models of …
Metallurgical coke has an optical texture or microstructure composed of anisotropic carbon in the form of mosaics and flow-type anisotropy as well as isotropic carbon or inerts. The anisotropic carbon is formed via the intermediates of nematic liquid crystals and mesophase. The physical and chemical properties of the coal ultimately control the …
Four bituminous coals of different origins and ranks and one industrial coal blend were carbonized at a semi-pilot scale at various temperatures to study the effect of heat treatment (i.e., different heating rates) on the structural evolution and hence the subsequent reactivity of the resulting cokes and their mechanical strength. The …
American Coke and Coal Chemicals Institute. ACCCI was formed in 1944 by companies interested in establishing a forum to discuss and act upon issues of common concern to the metallurgical coke and coal chemicals industry. Today, ACCCI members represent over 95% of the metallurgical coke produced in the U.S. and Canada, including both …
